That's how you know. Real mikuni or kehin say it. Chinese copies dont say anything on them.

You will find name brand carburetors have the name casted into the body of the carburetors.  Here’s a few images and what to look for.

Yep a good carb. So go through the carb and the manual and set it where it needs to be.  Then double check the choke as well and see that it’s properly seated.

It say mikuni I was looking for something Chinese that name is still Chinese 

Mikuni is actually a Japanese company.

China  can  produce some  junk parts , but unfortunately  so  can  Canada  and  the US.

China is also  capable of producing some very  high quality  products , and if you  look  closely  you'll  find an  uncomfortably large number of  "American"  or "Canadian" products  containing some Chinese  made  parts in their  makeup.  Dismissing  any  countries  products  as junk  out of  hand  is  foolishness in the extreme.

As far  as carburettors  are concerned,  unless it  is  corroded  badly, very  few  actually  need to be replaced..  They  all  can  be  cleaned but attention to detail  is  needed to  get every  passage and port / jet cleaned and unplugged . .Too often  tiny holes  in jet tubes  and  carb throats are missed.  The only  carbs  I've ever seen that  needed replaced  were some on such things  as weed eaters where the carb is plastic with some  jets and  parts  non serviceable  and plugged from  being  unused too  long  with old gas in them .

Bear in mind that some Chinese carbs are dead ringers of the Japanese produced ones like Mikuni right down to the name on them. Even though they look the same, I've found some that have jets that don't interchange.

If you cannot find a lift then maybe stiffer shock springs would help out.

Usually it’s a batter of creating shock mount extensions. Just a couple inches and you should t have to mess with lengthening the steering stem.

      I've got a king quad 750cc has anyone converted the fuel pump relay to a stronger fuel pump relay on there king quad?

      posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
      -fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
      -along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
      -I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
      -can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
      -it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
      -I THINK it has a mikuni model x carb - diaphragm is ID 26mm  OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
      -last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
      -any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law

      What is the opinion on carb kits? What's one of the better brands of aftermarket? OEM is always preferred but not practical, chinese cheapie is never a good option. 
      Thoughts ?

      Problem: The ATV starts and runs at idle perfectly. But as soon as I open the throttle, the engine starts to slow down until it stops. On the attached video you can hear the sound of how it works: see video below
      Prehistory: there is a Polaris Sportsman 500 1998, which for about 1.5 years stood in repair, including also replacing CDI with one taken from the same ATV. Finally, the vehicles were on wheels, traveled several kilometers and overheated - forgot to fill the antifreeze Came back home in small moves. The next trip started well, but after 10 km there was a feeling of a small drop in power (even as the vehicle got warm completely) but still drives. Next trip - the situation is repeated. The next test of ATV through time and a huge loss of power from the very beginning. The engine sneezes, does not want to go more than 5 mph.

      What has been done: the carburetor has been replaced with a new one (inexpensive, $ 40), a new spark plug, a new ignition coil, the engine head has been removed, the piston is in good condition, valves were corrected - but the problem was definitely not in them.

      Ignition control unit is suspected. Who faced similar? Please help in solving the problem.
      Thanks in advance.
